Self-contained insect killing device


Blood borne disease is a huge issue in Zambia/Africa, which lowers the quality of life for infected individuals, and lowers economy of affected areas. Diseases such as Malaria, Trypanosomiasis (Sleeping sickness), Filariasis, Dengue fever, Yellow fever, and Leishmaniasis are all diseases which are prominent in Africa and spread by airborne insects.


In order to combat the spread of blood borne disease through insect bites in Zambia, We are currently designing a lower power, low maintenance, self-contained, insect killer.
This will benefit its stakeholders in two ways, detracting insects from biting humans when in close proximity, and lowering insect population in stakeholders home environment overall.

How it works

It will attract mosquitoes and other flying insects which are in close proximity, without unnecessarily drawing them in from further afield. It will operate in the same fashion as a this "bug zapper" - - (Section 9), however with a lower power consumption so that it can be powered easily, using this method:

Using same principles as this Bicycle generator -
However with only one wheel and a handle. power generated will be stored in a battery producing DC current. Using the most effective method electrical power will be stored in a battery, this will be used to:
a) light a small led light (perhaps with UV functionality) to attract airborne insects.

b) to charge a wire mesh with enough charge to kill a fly when touched.

Total design will be low in cost and maintenance can be performed by stakeholders with help of a guide book.

What we would like to discuss on here are current design areas:

I. Pumping the handle must store enough power to: a) light the LED for 6-8 hours while stakeholder sleeps, and b) zap a sufficient amount of insects throughout the night (10 - 30 rough estimate).

• We must figure out power output ratings for LED and zapper circuit sufficient to kill insect, and power input rating for hand pump.

• In order to conserve energy, would a movement detection activator be beneficial to the zapper circuit? So that it is only switched on when needed. Alternatively a capacitor in the circuit to charge the zapper to a fatal level could be incorporated as a form of saving energy.

II. This must not disturb stakeholder while sleeping.

• A visor to semi conceal the light at night, so it is enough to attract an insect when flying near to stakeholder, but not enough to disturb stakeholder. This may make design more complex, and less maintainable as moving parts can be broken.

• Two light settings is an option, brighter for night use when stakeholder is awake, dimmer for when stakeholder is sleeping. However again a switch to alternate is another moving part which can be broken, lowering maintainability (further calculations to determine power consumption would be made).

III. Should dual functionality be incorporated? (e.g. light for stakeholder to see at night & fly killer), this would eliminate desire for stakeholders to repurpose the light and risk rendering it useless
